Dynamic Flow Equation Adjustment

Continuous adaptation of the flow equation to reflect variations in the stress state.

Compatibility with conventional simulators

Integration with existing simulators, without the need for extensive modification.

Improved Accuracy

The removal of rock compressibility and the inclusion of volumetric deformation result in more accurate simulations.

The problem-solution approach

Conventional reservoir simulators do not take into consideration the variation of rock’s stress state, which can lead to inaccurate simulation results.

What is it?

The innovation presented refers to advanced methods of partial coupling between a geomechanical simulator and a conventional reservoir simulator. These methods adjust the flow equation of the conventional simulator considering variations in the stress state of the rock, bringing it closer to the solution of the full coupling scheme.

How it works

By employing an iterative partial coupling scheme, the method reaches convergence, providing a solution that resembles the obtained by full coupling schemes. By removing the influence of rock compressibility and incorporating volumetric deformation, the flow equation is refined for a more accurate simulation.
